Procedure

To a THF/ethanol(10:1) solution of 3-(2-Phenylsulfanyl-acetylamino)-5-trifluoromethyl-benzoic acid methyl ester (252 mg, 0.68 mmol) was added sodium borohydride (46 mg, 1.4 mmol), and the mixture was stirred at 65° C. for 2 hours. The reaction mixture was left overnight. The mixture was diluted with ethyl acetate, washed with 1 N HCl (2×) and brine. The organic layer was dried over MgSO4, filtered and stripped. The crude product was purified by flash chromatography on silica gel eluted with hexane/ethyl acetate (4:1) to give 126 mg of N-(3-Hydroxymethyl-5-trifluoromethyl-phenyl)-2-phenylsulfanyl-acetamide in 54% yield.
